We present here a review of the photochemical and electrochemical applications of multi-
site proton-coupled electron transfer (MS-PCET) in organic synthesis. MS-PCETs are redox …

While remarkable progress has recently been made for the direct C− H‐functionalization of
azines, its application is still limited by a lack of accessible functional groups (primarily …

Efficient excited-state electron transfer between an iron (III) photosensitizer and organic
electron donors was realized with green light irradiation. This advance was enabled by the …

Photocatalyzed organic synthesis transformation is a remarkable green synthetic strategy
because of the advantages of operational simplicity, high chemoselectivities, cheap, and …

Quaternary pyridinium compounds are valuable intermediates in organic synthesis, which
have gained immense popularity in the synthetic community. The application of transition …

Abstract π‐π stacking and ion‐pairing interactions induced the generation of α‐amino
radicals under the irradiation of visible light without the requirement of an expensive …

Heterocyclic N‐oxides are prevalent in numerous natural products with broad applications in

In the early days of synthetic organic chemistry Hantzsch esters (HEs) were bio‐inspired
hydride donors and often used for the reduction of C= X (X= C, N, O) bonds. Recently, it has …

Novel approaches for N-and O-desulfonylation under room temperature (rt) and transition-
metal-free conditions have been developed. The first methodology involves the …

Functionalization with C1‐building blocks are key synthetic methods in organic synthesis.
The low reactivity of the most abundant C1‐molecule, carbon dioxide, makes alternative …
